“…Centralized decision on the organization of data center heterogeneous infrastructure proposed in the papers has some drawbacks including reliability support, cost of obtaining a complete and current network conditions, low scalability [18,19]. We assume that the development of a fully decentralized solution is the best option; however, in this case, there is a problem of interaction between the controllers of autonomous systems.…”

Nowadays, we see a steady growth in the use of service-oriented cloud applications in modern business. However, there are some issues related to the placement of service-oriented cloud applications in the software-defined infrastructure of the virtual data center. The goal of optimization is to control the service-oriented cloud applications within data centers. The advantage of modern infrastructure virtualization is the possibility to use software-defined networks and software-defined data storages. However, the existing optimization of algorithmic solutions does not take into account the specifics of working with multiple class service-oriented cloud applications types. The paper describes the models which describe the basic structures of service-oriented cloud applications including: a level distribution model of the software-defined infrastructure with the technology of cloud applications containerization, a generalized model of a service-oriented cloud application, a model of virtualization of service-oriented cloud applications based on containers. Besides, we developed the efficient algorithm for optimizing the technology of containerization of cloud applications and services in the virtual data center (VDC) infrastructure. We propose an efficient algorithm for placing applications in the infrastructure of a VDC The optimization of the placement of serviceoriented cloud applications based on the VM template and containers with VDC disabilities infrastructure is reduced to packing in containers. Besides, we generalize the well-known heuristic and deterministic Karmakar-Karp's algorithms. During the experimental studies, we have found that the use of our algorithm enables to decrease the response time of cloud applications and services and, therefore, to increase the productivity of user requests processing and to reduce the number of refusals.

The paper focuses on cooperation between cloud and network operators, as well as on fitting particular routing strategies to various cloud services. Three cooperation models are presented, analyzed and compared in the paper: the proposed model and two widely used reference models. The main difference between the models is the set of information being exchanged between the involved parties. Additionally, we analyze the applicability of four fitting schemas for each considered model. It is shown that the proposed model, alongside with an appropriate fitting schema, is able to reduce the blocking probability of cloud services requests. At the same time, thanks to the use of green anycast strategies, it is able to significantly reduce carbon dioxide emission.

“…The compute & storage (sub-)controller controls the computing and storage resources. The design of NO is motivated by the SDI resource management system in [10], which is used to controls and manage the underlying networking & computing resources in a wired network environment. The NO proposed in our paper, controls and manages the underlined network fabric and the corresponding compute & storage resources for a multi-RAT virtual wireless access network.…”

“…European commission's co-funded project, FP7-iJOIN [8] is investigating the use of cloud computing for a RAN as a Service (RANaaS) paradigm. Due to its added flexibility in network designing, software defined networking (SDN) is being seen as a crucial driver to virtualize wireless access [9], [10], [11] and core [12]. To enable a shared, elastic, virtual wireless network infrastructure, cloud computing is also being envisioned as a crucial component [13], [14], [15].…”

Virtualization is seen as a killer application of software defined networking (SDN). Virtual radio access network (RAN) is an emerging concept for 5G and beyond 5G networks and it is gaining increased attention from both academia and industry alike. Moreover, due to the current telecommunication trend of increasing network traffic and decreasing revenue, telecom operators all over the world are looking for network function virtualization (NFV) to reduce network deployment and running cost by maximizing resource sharing. In this paper, we classify virtual RAN into three possible PHY-MAC models that leverage SDN for virtualizing the underlying RAN substrate. A novel multi-criteria utility function is also proposed to evaluate the trade-offs between network cost and achievable QoS from PHY-MAC layers perspectives of these virtual RAN models. Analytical results show that a hybrid virtualization model attains the optimal balance between network cost and QoS and hence is the best virtual RAN model.
